Subtracts one unsigned integer value from another, performs an overflow check, and pushes the result onto the evaluation stack.
Assembly: mscorlib (in mscorlib.dll)
The following table lists the instruction's hexadecimal and Microsoft intermediate language (MSIL) assembly format, along with a brief reference summary:
Subtracts one unsigned integer value from another with an overflow check.
The stack transitional behavior, in sequential order, is:
value1 is pushed onto the stack.
value2 is pushed onto the stack.
value2 and value1 are popped from the stack; value2 is subtracted from value1 with a check for overflow.
The result is pushed onto the stack.
OverflowException is thrown if the result can not be represented in the result type.
This operation is performed on signed integers; for floating-point values, use Sub.
The following Emit method overload can use the sub.ovf.un opcode:
